She said Clark went back into the burning apartment and saved one of the dogs, which had been hiding from the fire.

Tyler said she didn't see Clark come out of the building with the dog, because she was trying to catch the other dog, which had gotten outside.

Bruschi said Monday Clark did go back into the burning apartment to try to find the dog and received additional burns, but that firefighters rescued the animal.

He said the dog had minor singeing from the fire.

Tyler was also upset that the 19-year-old man wasn't named. Police earlier said they were still investigating the man's involvement in the explosion and lab, and think he was inside at the time of the explosion.

Bruschi said Monday they are still not releasing the man's name because there is a pending investigation of a crime and the man "could be a victim of violent crime."

So far, neither of the injured men has been interviewed, the sergeant added, and neither has been charged.

Charges are pending an investigation underway by the Butte County Sheriff's Special Enforcement Unit, Bruschi said.

Investigators were able to go into the apartment on a search warrant at 6 p.m. Saturday, after the fire had been cool enough to enter.

The two-bedroom apartment was the only one damaged.

Oroville Fire Department, El Medio Fire Department and Cal Fire-Butte County also responded to the incident.
